I purchased this new about a month ago, but I no longer have a need for it, so I'm offering it to someone who does. It's in excellent condition, having only been unpacked and fitted. I believe it should fit 16-inch thin-body semi-acoustic guitars like the ES-335. While the length is quite tight for a Gibson ES-335, it's designed to be carried on your back, and the guitar will sink in slightly due to its weight, so I don't think there's anything to worry about. However, it may be necessary to take care with guitars that have longer headstocks. There's quite a bit of room on the body side. Even with a 335 inside, it feels loose, but it secures surprisingly well when you close the zipper. Please note that a rain guard was not included when I purchased it. Instant purchase is welcome. Please make any requests for discounts within reasonable limits. I plan to ship it via Yamato Transport, wrapped in bubble wrap. Thank you for looking.
